    They occupy the same bar in the service equipment or main panel.

    No offense meant, but shouldn't common topics like this be covered in the training courses? Isn't there any requirement to shadow an experienced inspector before doing this on your own?

    I commend you for asking questions as that is how we all learn. But how good can the inspection be when the common topics still need to be covered?

    Couple of black conductors there need to be properly marked as grounded/neutral conductors.

    I see one grounded conductor and it is white.
    I don't see a grounded conductor for that 100A breaker on the left.

    There is no requirement that a grounding electrode conductor or bonding conductor be green.

    Gunnar - For some reason he deleted his question about whether neutrals and grounds needed to be on the same bar in the service equipment.

    Wow. I just noticed that.

    WHY do original posters do that???? Makes the whole thread useless.

    John,

    Thanks. I thought I was being EXTRA dense today. Good to know that I am just regular dense.

    If the wires are feed in thru conduit, I believe you would have to duct seal
    around all the wires to seal the conduit openning.

    I have never heard of such a requirement.

    Peter,

    I believe he is referring to sealing required for raceways which go down into the ground.

    BTW, what section of the NEC governs the splicing of SECs?

    Jerry, Since I'm a little north of you, I'm not familiar with the NEC but doesn't that sentance refer to splicing of the actual feeder cable (ie: extending it) and not splicing the branch circuit wires to the feeder (as in lack of neutral bar) ?

    Also, does the NEC allow all the branch circuit wiring to enter and pass through the main-switch compartment ?

    Just curious.

    Joe,

    The question was about "service entrance conductors", thus the reference to splices for service entrance conductors, not feeders or branch circuits.

    Also, does the NEC allow all the branch circuit wiring to enter and pass through the main-switch compartment ?
    No. I believe you are referring to using the panel as a "raceway", i.e., "does the NEC allow all the branch circuit wiring to enter and pass through", and all the conductors in the panel are to be terminated in that panel, either at the grounding terminals, neutral terminals, or at an overcurrent device. This means that "passing through" is not allowed.

    Sorry Jerry, I thought we were both talking about the photos in post # 15 above.
